Introduction
Steel tube is sold by weight, by the foot, and by the stick — and the price you actually pay depends on which of those three the supplier leads with. A frame whose steel weighs 671 lb might be quoted at $1,170 by one yard and $1,540 by another, and both quotes can be “correct” for their pricing model. Understanding how tube pricing works turns that gap from a mystery into a comparison you can make in minutes.
The Steel Tube Weight Calculator gives you the weight side of the equation — pounds and kilograms for any size, wall, and length. This guide covers the money side: how tube is priced, typical planning ranges, a worked cost example, and where the hidden costs (cuts, waste, freight) show up. All prices below are typical US planning ranges; verify with local suppliers, since steel prices vary by region, quantity, and market conditions.
How Steel Tube Is Priced
Suppliers price tube in three overlapping ways, and the cheapest option depends on your quantity:
- Per pound: the mill/service-center convention. Multiply your total weight by the per-lb rate. Typical retail planning range: $1.50–$3.00/lb at metal supermarkets and small yards; $0.80–$1.50/lb at full-service steel distributors when buying in quantity.
- Per foot: common at retail counters. A 2×2×1/4 in stick at 5.59 lb/ft and $2.00/lb costs about $11.18/ft. Retail per-foot pricing usually carries a markup over per-pound because it bundles handling.
- Per stick: whole 20-ft or 24-ft lengths, the way most small buyers actually purchase. A 20-ft stick of 2×2×1/4 in (111.8 lb) might list at $170–$280 depending on the yard and the market — equivalent to roughly $1.50–$2.50/lb.
Because weight is the common denominator, the calculator is your comparison tool: convert every quote to cost per pound and the cheapest supplier reveals itself. For turning a cut list into that total weight, see the estimating guide.
Typical Planning Ranges
Use these as budgeting figures, not quotes — steel is a commodity and prices move:
| Item | Typical planning range |
|---|---|
| Bare HSS, retail per-lb | $1.50–$3.00/lb ($3.30–$6.60/kg) |
| Bare HSS, distributor per-lb (quantity) | $0.80–$1.50/lb ($1.76–$3.30/kg) |
| 20-ft stick, 2×2×1/4 in (retail) | $170–$280 |
| 20-ft stick, 4×4×1/4 in (retail) | $370–$610 |
| Galvanized premium over bare | +15–30% |
| Per-cut fee (chop saw) | $2–$5 per cut |
| Local delivery | $50–$150 |
| Fab-shop welding labor | $75–$150/hr |
Wall thickness is the biggest cost lever you control: for the same frame, 2×2×3/16 in (4.32 lb/ft) carries about 23% less steel than 2×2×1/4 in (5.59 lb/ft), so it costs about 23% less in material. Choose the wall for the structure (with an engineer where loads matter), not for the invoice — but know the trade-off exists. Material choice details are in the material guide.
Worked Cost Example
Take the frame from the complete guide: six pieces of 2×2×1/4 in × 20 ft = 670.8 lb (304.3 kg), plus a 10% cutting allowance = 737.9 lb (334.7 kg).
Option A — priced per pound at a distributor, $1.25/lb: 737.9 × 1.25 = $922 (about $2.76/kg).
Option B — priced per stick at retail, $220 per 20-ft stick. Seven sticks needed (six pieces plus allowance): 7 × 220 = $1,540.
The $618 gap is the retail markup plus whole-stick rounding — not a mistake. The lesson: for projects over a few hundred pounds, a distributor quote on per-pound pricing usually beats retail per-stick pricing by 30–40%. Below that, retail convenience wins because distributors often have minimum orders or surcharges.
The Hidden Costs: Cuts, Waste, and Freight
Material is only part of the invoice. Budget these too:
- Cutting: if the yard cuts your sticks, $2–$5 per cut adds up on a 20-piece cut list. Owning a chop saw or band saw pays for itself quickly on repeat projects.
- Waste and offcuts: a 5–10% cutting allowance is standard; complex cut lists with odd lengths can push real waste to 10–15%. You pay for every pound delivered, not every pound installed.
- Freight: a 738-lb order is a truckload-scale delivery for a small yard — budget $50–$150 locally. Picking up with your own trailer is often free but costs your time and fuel.
- Fabrication labor: a simple welded frame (cut, fit, weld, grind) typically runs $200–$600 in shop labor for a small project, more for complex assemblies. This is where DIY vs hiring a fabricator becomes the real cost decision.
Five Ways to Spend Less
- Design to stocked lengths. A cut list that nests cleanly into 20-ft sticks wastes less steel and buys fewer sticks. The pro tips guide covers nesting.
- Quote per pound, buy per pound. Convert every quote to $/lb before comparing suppliers.
- Right-size the wall. Don’t default to 1/4 in everywhere — thinner walls where the structure allows cut 20–30% of material cost.
- Combine orders. Distributor pricing tiers reward total pounds; one 2,000-lb order beats four 500-lb orders.
- Ask about drops and remnants. Short offcuts from previous jobs often sell at a discount and are perfect for small brackets and gussets.
